sUc'rioN CLEANER.

Application led'October 9, 17922.- Serial No. 593,197..

My invention relates to vacuum sweepers. 'The main object of my invention isA to provide an improved sweeper adapted to easy and inexpensive manufacture and efib cient operation.

A further purpose is to lprovide'improved connections whereby the fan of a non-electric sweeper may be thrown into gear and operated y by the forward motionv ofthe sweeper along the viioor and disconnectedk from driving connection with the wheels of the sweeper as soon as thesweeper stops,

lpermitting return. of the' sweeper 'without reversal in the direction of the fan. i 15 A further'purpose is to provide an im'- proved drive between the shaft vof the sweeper wheels and the fan and brush.

Further purposes-will appear in lthe specification and claims. i n f I have lpreferred toV illustrate my invention by one main form'` only, selecting the form because of its value in illustrating the principles of my invention.

Figure 1 shows in a sectional elevation of the form selected.

Figure 2 is a section through line 2-2 of Figure 1.

Figure 3 isa section through line 3;-3 of Figure 1. f 1

Figure 4 is a section through line 4-4 `of Figure 1.

Figure 5 is a fragmentary section upon line 5-5 of Figure 1.

In all. the drawings like numbers refer to like parts.

Describing. myl invention in illustration and not in limitation In the form shown in the figures the shoe and other parts are preferably made of cast metal rather than of pressed metal. The fan is of the general type disclosed and claimed in my Patent No. 1,350,724 having radial inlet ports and discharge ports. The supporting wheels 112 and 113 are carried upon a vertical pivot 114. The fan 115 is placed directly over the shoe and the fan shaft 116 extends down into the shoe through bearing 117 rigid with the shoe. The fan is shown as provided with radial inlets 115 and circumferential outlets 1152. The shaft carries a worm 118 to engage the worm gear 119 upon'the shaft 120'of the rotary brush 121. The shaft 120 1s supannulus anda hollow gear 144 connected by .mitting' the handle to be set angularly with ported in bearings 122 and 123 rigid'with the casing of the shoe.. The discharge duct yfrom the fancomprises lateral portions 124 and 125 connected together above the fan through fa duct 126 to a discharge port 127 leading to the-dust bag which is not shown,

being no part of the invention. ,i i

Ysingle c'asting'128 forms the shoe and lowerand side portions ofthe fan casing r' and the pillow-block bearings 129'and 130 for the verticalpivot 1'14'of'the Wheels 112,

113, as well asthe lower' portion'131 of the 06 gear casing.

The vertical shaft 116 of the fan and lworm passes through thebearing 132 ofthe casting 133 and at its upper end carries the spur gear 134 in mesh with the .large gear 135 that is rigidly and axially connected withthe smallspur 136 which' through the -idler spur 137 is' driven by the large gear 138l upon the vertical pivot 114 of the wheels. One of the large wheelsdrives the spur gear 138 through shaft 139, disc 140, latch -141 carried by the disc, `an annulus 142 entical pivot in any desired position to prevent turning.

The construction is suited to easy manufacture from `a very few castings only. In operation the direction yof the wheels 112 and 113 is controlled by the shaft 114 iiXed at its bottom in the bearing 150 for the axle for these wheels asbest seen in the fragmentary view of Figure 5. Meantime the fan mechanism is driven through gear 138 by which also the brush is driven.

Variations andy modications will doubtless become evident to others skilled in the art to meet individual whim. or particular need, and it is my desire to claim all such variations and modifications in so fary as they fall within the reasonable spirit and scope of my claims.

CIJ

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a suction sweeper, a pair of driving wheels, a horizontal shaft connecting gears rotatably mountedV on vthe verticalV shaft, the lower meshing with the first named gear, a handle connected to the vertical shaft to lswing' the horizontal shaft about a vertical axis, a shoe adapted to be supported upon the floor, afan above the shoe fand connections between the upper gear upon the vertical shaft and the fan to drive the fan. 'p

' 2. In a suction sweeper' a horizontal shaft, driving wheels thereon, a vertical shaftwith 'which the .horizontal shaft swings bodily, gearing rotatably .mouutedon the vertical shaft, a handle connected with the vertical shaft to swing horizontally, a shoe, a fan and 'driving connections between fthe fan and the gearing on the one side and between the gearing a d the driving wheelslon the 'otheri l. f v v 3. In a suction cleaner, ia. easing, supporting `wheels to roll on a Hoor, a .horizontal shaft upon which the wheels are mounted, a

sleeve thereabout, a vertical pivot rigid with the sleeve, a bearing therefor, a member rigidly connected to the end ofthe pivot, a handle horizontally pivoted totheA member, a lu'gfon thegoasing and close to the member, .and a screw therethrough adaptedto lock the member relatively to the lug.

4 Ina suctionjsweeper, a roller support 'edeasing having openings at the top forming "fan'iniets, a fan having blades sweeping past said inlets andV turning about a vertical faxis, walls ,eircumferentially enclosing portions ofthe fan, apertured'for outlets and ing wheels for driving the gear upon the vertical shaft. f l

In' a suction sweeper, a roller-supported casing havinginletv openings at the. top forming fan inlets, 'a fan having blades sweeping pastA said inlets and turning .about a vertical axis, Walls circuinferentially ,en-

closingr portions of the fan, apertured Vfor outlets and forming adistributing outlet channel at the. sides connected .with said outlets, a lvertical driving shafty for said fan, a driving gear at the upperend of the shaft, bearings for the shaft above the'fan; a bearing for the lower end of the shaft, a Worm upon the shaft` below lthe fan, a worm gearA connecting with the worin, a rotary brush, a shaft therefor directly driven by thev worm gear, a pair of driving wheels and clutch connection from said driving wheels for driving the gear upon-the vertical shaft. Y y Y Y 6. In a suction sweeper, a pair of guiding Wheels, a horizontal vshaft connecting. the wheels, a gear upon the shaft, a bearing for the shaft, aV vertical shaftrigidwithfthe bearing, two rigidly connected gearsV rotatably mounted 'on the vertical shaft, the low- ,Y

er meshing with the first Vnamed. gear, a han-- `dle' connected tothe vertical shaft to swing the horizontal shaft about a 'vertical a'Xis, a shoe adapted to'be supported upon iioor, a fan above the shoe, connections 'between the upper gear yupon the verticalv shaft and the fan to drive the fan and clutch 'mechanism permitting one of the wheels tov move independently of the other.
